BACKGROUND OF THE DISCLOSURE

Consumers of cosmetic products actively seek out multi-functional, newproducts which are pleasing to the senses, both on application and inuse, and which do not sacrifice the functional performance. Oneimportant functional element of such compositions is their ability tostyle the hair without weighing it down. Many consumers seek hairproducts which have excellent style memory, cosmeticity, and shinewithout heavily coating the hair strands, and thereby weighing the hairdown and often times exhibiting a brittle or crunchy film. The resultingfeel and texture of the hair after the application are importantelements of such commodities. While different technologies and productsexist in the market for hair styling products, there is still a need forimprovement in these areas.

Traditional hair cosmetic treatment compositions on the market appear invarious forms. They can range anywhere from solutions, foams, gels,creams, waxes, serums, to aerosols and can impart a variety of levels ofconditioning depending on the state of the hair. However, theseconventional cosmetic compositions have limitations and thus are lessappealing to the consumer. Such limitations may include sticky or greasyproducts, irritation on the scalp, a heavy or oily coating on the hair,leading to decreased style memory or hair that lacks volume and a cleanfeel. Therefore, there is still a need to improve currently marketedcommodities in order to provide the consumer with innovativeformulations that present both sensory and functionality perspectives onhair treatment products.

Thus, the object of this invention is related to a composition andmethod of styling hair utilizing hair compositions which will impartshine benefits, volume, and good style memory to the hair, but will notresult in any product build up or leave the hair feeling heavily coated,crunchy, or brittle.

BRIEF SUMMARY OF THE DISCLOSURE

It has surprisingly been found that compositions and methods of stylinghair using a two phase system comprising at least one alkoxysilanehaving at least one solubilizing functional group and an aminosubstituent, at least one water-soluble metal salt, at least oneacidifying agent, and at least one silsesquioxane resin impart stylingbenefits to the hair. The hair treatment composition is also emulsifierfree.

Thus, the present invention is directed to a cosmetic composition fortreating hair containing:

-   -   (a) a first phase comprising:        -   i. at least one alkoxysilane having at least one            solubilizing functional group and at least one amino            substituent;        -   ii. at least one water-soluble metal salt;        -   iii. at least one acidifying agent; and        -   iv. a cosmetically acceptable carrier comprising water;    -   (b) a second phase comprising:        -   i. at least one silsesquioxane resin; and        -   ii. at least one volatile solvent.

FIG. 3 is a SEM image which shows the surface of hair treated by acomposition containing 5% by weight APTES and 3% by weight lactic acidin water. There are no solid depositions on the hair surface. The imagedemonstrates that the combination of lactic acid and APTES reduced orinhibited the polymerization of APTES on the hair surface, and thus,improved the penetration of APTES into the hair fiber.

FIG. 4 is a SEM image of the surface of a hair fiber treated with wateronly.

FIG. 5 is a SEM image of the surface of a hair fiber treated with theinventive composition. The image depicts the formation of a film on thehair after being treated with the inventive composition comprising thefirst and the second phases.

With 10% byweight of the second phase in the total weight of the composition, alight weight, smooth, and natural finish was observed on the hair. Thislow percentage of the anhydrous phase was found to be ideal forconsumers with fine hair types. With 90% by weight of the second phasein the total weight of the composition, a more rigid, high shine finishwith added texture was observed on the hair. This was found to be idealfor consumers with coarse hair types. Thus, the proportions of the firstphase to the second phase may be varied within the weight ratio spectrumto create different products for all individual hair types.

 2. The composition of claim1, wherein (a)(iv) comprises at least one non-volatile solvent.
 3. Thecomposition of claim 2, wherein the at least one non-volatile solventcomprises a polar or non-polar oil.
 4. The composition of claim 2,wherein the at least one non-volatile solvent comprises C12-C15 alkylbenzoate.
 5. The composition of claim 1, wherein the weight ratio of (a)to (b) is from 10:90 to 90:10.
 6. The composition of claim 1, whereinthe weight ratio of (a) to (b) is from 20:80 to 80:20.
 7. Thecomposition of claim 1 comprising less than 0.25% by weight ofemulsifiers, based on the total weight of the composition.
 8. Thecomposition of claim 1, wherein the composition is sprayable.
 9. A spraybottle comprising the bi-phasic composition of claim
 1. 10. A method ofstyling hair comprising combining the first phase (a) and the secondphase (b) of the bi-phasic composition of claim 1, and spraying thecombination on the hair.
 11. The method of claim 10, further comprisingheat styling the hair after spraying the combination on the hair.
 12. Abi-phasic composition for styling hair comprising: (a) a first phasecomprising: (i) about 0.5 to about 20% by weight, based on the totalweight of the first phase, of 3-aminopropyltriethoxysilane; (ii) about0.1 to about 5% by weight, based on the total weight of the first phase,of magnesium sulfate, calcium sulfate, or a mixture thereof; (iii) about0.1 to about 20% by weight, based on the total weight of the first phaseof lactic acid, citric acid, or a mixture thereof; and (iv) about 5 toabout 80%, based on the total weight of the first phase, of acosmetically acceptable carrier comprising water and a non-volatilesolvent other than water; and (b) a second phase comprising: (i) about 1to about 15% by weight, based on the total weight of the second phase,of polypropylsilsesquioxane resin; and (ii) at least one volatilesolvent selected from the group consisting of isododecane,isohexadecane, and a mixture thereof; wherein the bi-phasic compositionhas two visually observable layers and is free of pigments.
 13. Thecomposition of claim 12 comprising about 1 to about 60% by weight, basedon the total weight of the first phase, of the at least one volatilesolvent.
 14. The composition of claim 12, wherein (a)(iv) comprises atleast one non-volatile solvent.
 15. The composition of claim 14, whereinthe at least one non-volatile solvent comprises a polar or non-polaroil.
 16. The composition of claim 14, wherein the at least onenon-volatile solvent comprises C12-C15 alkyl benzoate.
 17. Thecomposition of claim 12, wherein the weight ratio of (a) to (b) is from30:70 to 70:30.
 18. The composition of claim 12, wherein the compositionis sprayable.
 19. A spray bottle comprising the composition of claim 12.20. A method of styling hair comprising combining the first phase (a)and the second phase (b) of the bi-phasic composition of claim 12, andspraying the combination on the hair.
